iMPROVEiVlENT lN GANG=PLQWS.

Specification forming part of Letters Patent No. 33,206, dated November 19, 1872.

To all whom it may concern:

Be it known that I, MARSHALL S. OURTISS, of Bradford,-in the county of Stark and State of Illinois, have invented a new and useful Im provement in Gan g-Plows; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same,.reference being had to the accompanyin g drawing making a part ofthis specification, in which- I Figure 1 is a perspective View, the near wheel being removed 5 Fig. 2 is a plan view, the seat and its supports being removed to show the other parts more clearly 5 Fig. 3 is a longitudinal elevation; and Fig. 4 is a plan and ion gitudinal view of the wedge 25 for elevating or depressing the plows.

Like letters in all the figures of the drawing indicate like parts.

The object of this invention is to afford free lateral motion to the axle and wheels of a gangplow, so as not to interfere with the direct progress of the plows; also, to eifect the raising or lowering of the points of the plows by means of the drivers foot; also, to throw or turn the axle forward, so as to elevate the beams and plows out of the soil when desired. The driver manages and guides the piows'and machine without leaving his seat, all of which will be hereinafter more fully explained.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

0 is a horizontal rod, on which the clevis-bolt f slides, (or rather the rod 6 oscillates to the right and left within-the eye of said bolt 1".) Said rod is horizontal and held transversely across the machine in proper slots or guides d d at either end, where the rod is also attached to-a vertical rod, F, passing through the platform B to the drivers foot. The staplesl Z on the beams GG allow the oscillation of the horizontal arm k of the liftingarm I to move freely without interfering with the direct progress of the plow, which might otherwise be the case if the arm I were attached rigidly to the beams. F is avertical rod, which passes downward through the platform B attached to the tongue 0, and terminating in branching arms which embrace either end of the transverse horizontal bar e. The ends of the latter slide in long staples or guides d (1 depending from and secured to the platform B. To the bar 0 is attached the eye of the bolt j, which freely slides thereon. The bolt f secures at once the rod 0, the clevis gto the beams GG, the clevis g to which the double-tree L is attached. The upper end of .the vertical rod F terminates above the platform B in a foot board or rest,

h, by which pressure is transferred to the point of the united beams G Gr. .A is an axle, mounted at either end on wheels, and hinged at b b to a platform, B, attached to the heel of the. tongue 0. A bar, I, is hinged to the front face of the said axle at it, and,passing to the rear down to the beams G G, terminates in a crosspiece, 7c, the ends of which slide in long staples Z l on either beam, so that the latter may be raised so as to, elevate the plows from the soil by raising a lever, D, from a horizontal posi- .tion and engaging the same in a notch near the seat E between the guides 11 g. This lever is pivoted at s, the smaller arm of the same being connected, by a link, a, with a short arm, m, fixed to the axle A. The drivers seat Eis supported by the standard 0' upon the plat. form, and by curved supports or guides 19 q upon the tongue or the platform, if required. Between the parallel guides 19 q is a notch or notches near the seat to act as detents for the lever D. The lever D for elevating the plows out of soil, or for locking the axle in a vertical position when the machine is at work, is pivoted at s on the tongue or on the platform, the shorter end being pivoted to a link, a, which is, in turn, pivoted to the end of an arm, m, projecting forward from the axle A. F is the vertical rod in the platform B, with a footboard, .h, near the drivers seat and branching below, and engaged with either end of a transverse horizontal bar, e, on which slidesthe eye of the clevis-bolt f. This bar 0 is confined at either end within the vertical staples or guides d d depending from and firmly fixed to the platform B, and is secured at either end by a nut from escape from said guides. G G, the plow-beams, which consist of parallel beams converging to a point at the clevis g, to which the double-tree L is attached, and are united by cross-pieces, and carry the usual plows H H, which have divided standards a c, or rather are provided each with an after-brace, the latter being firmly fixed to the beam, and the standards a c may be attached to the beams, 1

2 reason respectively, by a vertical bolt or terminal thread on the top of the standard and nut, which can be loosened to force the wedget further forward between the beam G and the pin to in the standard a to depress the polnts of the plows. The wedge is link-shaped, and tapers horizontally from one end to the other to render it of the proper wedge-form; at the same time, its being a link fits it for permanently inclosin g the neck of the standard and securing itfrom loss. (See Fig. 4.) I isa strong iron bar, hinged at t t to the front of the axle A and passing to the plow-beams G G, where it terminates in a transverse arm, is, which is engaged at either end in the staples l Zaffixed to the surface of the beams. The arm 70 projects beyond either staple at either end to allow of lateral motion.

The operation of this gang-plow is as follows The lever D, when let. fall to a horizontal position, locks and retains the axle A in its normal or upright position, as in Fig. 1. When the lever is raised it elevates the whole plow G G H H, both at points and heel, but much more at the heel, as in Fig. 8. The guides "at d permit the head or clevis end of the beams to rise by pressure upward against the vertical bar F. The lateral motion and device to obviate its effect upon the true course of the plows has been described above.

Having thus fully described my invention,

what I claim therein as new, and desire to secure by Letters Patent, is-

1. The plow, having a free lateral motion with respect to the wheels and axleAby means of the rod 6, arranged to oscillate within the eye of the clevis-boltf of the plow, in combination with slots or guides d d, hinged platform 13, and hinged iron I, having transverse arms is arranged to oscillate in slots or guides Z Z of the beams G G, substantially as set forth.

2. The vertical rod F with foot-board h, transverse horizontal bar 6, clevis-bolt f, and slots or guides at d, in combination with platform B having a hinged connectionwith axle A, so as to effect the raising or lowering of the points of the plows by means of the drivers foot, substantially as set forth.

3. The lever I), link a, and arm on of axle A with hinged platform B and hinged iron I, in combination with the notched parallel guides 12 q and beams G, in order to throw or turn the axle forward so as to elevate the beams and plows out of the soil, when desired, substantially as set forth.

In testimony that I claim the foregoing gangplow I have hereunto set my hand this 22d day of May, A. D. 1872.
